Question

我的个人ListBox有两个不同的ItemTemplates - 由TemplateSelector选择。这很好用，我在屏幕上显示了两个不同的ItemTmplates。

但我没有的是选择。所以我无法在ListBox中选择一个Item。使用键盘，它可以选择一个。

这是我的ContainserStyle的样子：

<Style x:Key="ListBoxItemStyleMain" TargetType="ListBoxItem">
            <Setter Property="Padding" Value="5" />
            <Setter Property="HorizontalContentAlignment" Value="Left" />
            <Setter Property="VerticalContentAlignment" Value="Top" />
            <Setter Property="Background" Value="Transparent" />
            <Setter Property="BorderThickness" Value="1" />
            <Setter Property="TabNavigation" Value="Local" />
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="ListBoxItem">
                        <Grid x:Name="grid" Background="{TemplateBinding Background}" RenderTransformOrigin="0.5,0.5">
                            <Grid.RenderTransform>
                                <CompositeTransform />
                            </Grid.RenderTransform>
                            <Grid.ColumnDefinitions>
                                <ColumnDefinition />

                                </VisualStateGroup>

                                </ContentPresenter.RenderTransform>
                            </ContentPresenter>

                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>

所以 - 正如你所看到的，我已经定义了一个选定状态。这是所有默认样式和模板 - 除了颜色。

感谢任何建议：）

发现它 - 我真的不清楚为什么我没有选择。因为当我插入一些内容项目（我目前还没有）时，选择工作正常。选择状态仍然有效 - 但你必须精确点击焦点边框：）

未显示Silverlight ListBox选择
